As of right now, it looks like Maryland's Jordan Williams will indeed test the waters and put his name in the 2011 NBA Draft. Williams' father all but confirmed to NBADraft.net that Williams will indeed put his name on the list and go through the pre-draft process.
Leon Williams, Jordan's father, confirmed with NBADraft.net's Rodney Halprin on Monday that "Jordan is testing the waters... but nothing is official, he is considering it but no decision has been made on him staying in the draft."
Williams does not appear to be close to hiring an agent, which means he could pull out and return to school. The deadline to do this is on May 8. Until then, Williams can go through the pre-draft process, talk to teams and get a better idea of where he might be selected.
Williams averaged 16.9 points and 11.8 rebounds in a breakout sophomore season, but the Terps missed the postseason. If he returns, the team would be much-improved on paper, with the emergence of Terrell Stoglin and a top recruiting class led by Baltimore guard Nick Faust coming in. Williams is considered a borderline first-round pick if he were to declare for the 2011 NBA Draft.
